In the mirror universe, Argashek was a Klingon councillor in the Klingon Empire during the late 23rd century. In 2288, he vehemently objected to Councillor Gorkon's suggestion that a few worlds should be sacrificed to double the Klingon military budget. Argashek was supported by his comrades Grozik and Glazya. (TOS - Mirror Universe novel: The Sorrows of Empire)
